Synchronome Repair – making a new pallet

Posted by: Raynerd In: Synchronome Clock Repair

I`ve not made any updates in a while as I`ve been working to get my gearless clock up and on the wall! I`m just waiting for the case to be built so in this time, I have a few jobs to do, first repairing this synchronome:

I`ve managed to source a pendulum bob and invar rod, so now I need to make a pallet and suspension.
Using the advice on the forums I started machining the new part:

Now I just need to speak to the guys on the synchronome group to find out how to fit the count wheel pawl.

hello raynerd,

i just found your blog. very nice pallet you made. in your post you mentioned you sourced a pendulum bob and invar rod. i am wondering about the bob. is it just a piece of round steel (or cast iron) or is there a compensation sleeve inserted?

best regards

kurt

Hi Kurt
The pendulum bob is apparently an original synchronome bob and it is simply a solid cast iron block! No compensation or such..

Thanks for taking the time to read and post.

Hello there Chris
Your pallet looks great. I am actually in exactly the same situation myself, in that I also have a Synchronome which is missing its pendulum. Could I possible take the liberty of asking for your help? Firstly, what sources of technical information are you using to gather dimensions etc (you mention forums). Also, the technical plan for the pallet which I can see in one of your photos… did you do that drawing yourself using a genuine pallet to measure and copy? Or is there a magical technical source somewhere out there for such technical drawings? Is there any way I could persuade you to send me a copy of it?
Many thanks for your help.
Stephen.

Oh i`m really really sorry! Nearly a month has gone and I`ve not replied as unfortunately I don`t get any notification of comments so you are best emailing for a quick reply. chris@raynerd.co.uk
I`ll email this to you as well but to answer a few questions, there are plans on the Synchronome Yahoo Groups documents section for the pallet and pendulum assembly. I also used the book by Hope-Jones called Electric Clocks and How to Make them. This book also has many of the key dimensions. If you need any help then please let me know although I expect by now you have sorted it out!
Chris

Welcome to Raynerd.co.uk

I`ve always wanted to learn more about engineering and electronics and my list of projects both complete and ongoing has been growing over the past few years. I like to document my progress more for my own understanding as much as anything, it helps keep me on track. I hope you can find something of interest to you, my clock building project is my priority but as you can see, I have many other builds I`m working on. Please leave a comment, it is nice to see people are reading!
